TOPIC: What is the sample rate of the SmartMotor

In the user guide referring to the WAIT command it says "Unless otherwise programmed with
the PID# command, the sample rate is about 4KHz". Does that mean it is some known value close to 4kHz, or does it mean it's somewhere around 4kHz but the exact rate is undefined or variable?

I am intending to use the sample clock to create some velocity profiles with accurate timing so obviously it's quite important!

I notice that in the example program for measuring execution time you have the following line:

d=c/4069 ‘Divide by sample time to get seconds per 1M operations

which implies the clock is running at 4069 Hz. Should that be 4096? It seems like a more sensible number, being 2^12.
